First of all, they are too far away for me to make them a realistic choise, and second of all, I beleive it is a waste of money. I am fully aware that the metal is better protected, but my car will be in a garage, and only be used a few times every year during summertime, so it is unlikely it will ever even see rain again. I am confident that a thick layer of epoxy primer after the sand blasting will seal off the metal from the enviroment just fine. All cavities will be filled with cavity wax once the car has been painted, and using the rotisory I can make sure it reaches every corner where it needs to go.After sandblasting, I would consider thermal metallization if I were you. Jyderup Sandblæseri can do both for you.
